To provide extreme accuracy for the .17 Magnum Rimfire caliber, the scope's elevation knob is precisely calculated to compensate for the elliptical drop of the .17 Magnum Rimfire with a 17 grain bullet. Once you complete the zeroing process at 100 yards, all you have to do is match the elevation turret indicator with 100 yards marking on the knob. From this point, turning the elevation knob to the desired setting can compensate your trajectory from 100 up to 300 yards simply.
